My honda cr-v 1999 is overheating how do I check the water pump is working?

the water pump will be working
what won't be working if fitted is
the viscous fan hub
radiator fans ,
coolant temperature sensor
fan relaypressure test the cooling system to check for cracked plastic tanks of the radiator
fan fuses
blocked radiator cores
head gasket
so if the fan is driven by a belt then replace the viscous fan hub
have a compression test done to check head gasket
have an auto electrician check the cooling system electronics and fans
have a specialist radiator shop do a flow test on the radiator and have an accredited service shop check the operation of the thermostat

How do I check if the water pump is working?

Hi Andy, Im AL the owner of Big As Auto Repair.

Andy, there's a lot of things that can cause an engine to overheat and pretty much the same on all engines. I don't what vehicle, engine size or year you have but, here the steps you need to take. (1) Check the coolant level, low coolant can cause overheating. (2) Check that the electric coolant fan motor is coming on if in fact its cooled by an electric motor and not a mechanical fan. If the fan is not operating properly or not coming on at all it will overheat. (3) After and only after the engine has cooled completely remove the radiator cap and start the engine and allowed it to reach operating temperature and watch the coolant in the radiator. It will overflow some until the thermostat opens, this is normal. BUT, if after it reaches operating temperature and it continues to blow coolant out and overheats, when the fan is operating then you may have 1 of 2 things happening. (A) The thermostat could be sticking closed. If it is replace it and re-test it again. (B) If it still blows coolant out after replacing the thermostat, you could possibly have a blown head gasket. BUT, DO NOT assume its a blown head gasket, have it checked to make sure. If this helps you out please give me a thumbs up on my auto-repair-website here:

96 honda overheats then cools while driving

If it is only overheating when your sitting still the cooling fans may not be coming on and pulling air thru the radiator. When you go down the road air is flowing thru the radiator and helping cool down the engine coolant.

Hi there I have a 1991 Honda Legend, It overheats

Some thing too check:
Make sure coolant level is up to line and clean (not dirty, do to clogged radiator, may need to be flushed or replaced).
Make sure air flow through the out side of radiator is clear (dirt, leaves, ect..) .
Make sure fan is working properly equip t (is not running too slow). Or Manual (belt driven) fan clutch is working properly, not loose or spinning too freely?
Check for broken or cracked fan blades itself.
Check radiator cap, (no gasket tears).
Could be thermostat going bad ?
Could be coolant temperature sensor/switch (from computer) going bad?
Check radiator hose(s) (too soft, may collapse)?
In some rare cases:
Timing could be off.
Could be water pump.
Could be blown head gasket(s).
Could have cracked head(s).
ECT..............Hope this was some help???

ok this is why we keep reciepts at our house. you have already bought everything you need to fix the problem. we just need to figure out what went wrong. lets start with the coolent level make sure you have plenty of coolent in the radiator. ok you hear the fans go on make sure they are turning. if thats good i would do the cheepest thing first. new thermostat make sure its the right one for your car the auto store can tell you. it could have seized up after sitting. also if you may want to look for that water pump reciept. just because something is new dosent mean that it works correctly, that goes for thermostat also. now if all of this doesent fix it there are 2 more things and it has to be one of them or both of them. [ important ]when you had this work done was the radiator flushed out and cleaned? if not- even if all these parts are changed you still have sludeg in your radiator that can go right into your new pump and clogg it or the thermostat or clogg the radiator itself whitch still may be a problem. i would start with a radiator flush AND a new thermostat. make sure you have fluid circulation if not its the pump again. i hope this gives you help REMEMBER NEVER WORK ON A HOTT CAR LET IT COOL COMPLETLY DOWN A SATURDAY MORNING PROJECT FOR SURE...

I have 1996 Honda Accord. The vehicle overheats, especially when the Air Conditioning is turned on. There is no thermostat in the car and the cooling fan doesn't work. Does it just need a new cooling fan?

If you run the vehicle with an inoperable radiator cooling fan you will overheat and destroy the engine. You will just make the problem even worse by running the aircon. The car should not be driven with an inoperable cooling fan.

A thermostat should be re-installed in the engine's cooling system and a new cooling fan installed.

If you have been running the vehicle with this overheat condition for some time you may well have already damaged the engine, the first sign of which may well be a blown head gasket and a damaged engine head.

If you damage the engine from overheating, repair costs can easily exceed the market value of this 1996 model car.

2000 Ford Taurus, V6, auto trans, new thermostat installed, still over heating, not sure if cooling fans are starting. Checked all fuses. Any ideas?

first i would check the cooling fan relays, when the temp gauge gets anywhere between over half and overheating you should hear the relays switch(it will make a clicking sound). but do not let the car overheat! Secondly the fans are controlled by the cooling fan temp switch/sender, this is located on the radiator, and you should check to see if the fan is getting power by using a volt-meter to check for the proper 12 volts. Finally if they still do not kick on you will need to replace the cooling fan motor(s).

The car overheats with new radiator and when I turn the heater and air on the needle comes back down to50% or normal. The overflow container is also cracked. 1994 Acura Legend

Change the thermostat and bleed the air out of the cooling system,make sure the cooling fans come on,and go off by themselves,with the defrost,and the ac off.

Honda Accord 20012.0L auto, Radiator fans is not working.

check the thermostat, the thermostat regulates water flow through your engine to cool it down sometimes they get stuck open or closed, remove it and put it through a simple test
grab a cup of cold water and a glass of hot water drop it in one then the other, you should be able to see if it opens and closes
